27、策和農(nóng)業(yè)發(fā)展戰(zhàn)略,提出了農(nóng)業(yè)可持續(xù)發(fā)展的以深松為主體的少免耕等保護性耕作技術(shù)。在所有對策中,都把耕作機械的發(fā)展方向作為戰(zhàn)略重點。西方發(fā)達國家早在20世紀 70年代就開始研制和推廣適應(yīng)高產(chǎn)農(nóng)藝要求的新型農(nóng)機具,研究開發(fā)節(jié)本增效、保持生態(tài)環(huán)境和保護耕法的作業(yè)技術(shù)及配套機具。</p><p> 傳統(tǒng)農(nóng)具在結(jié)構(gòu)上不斷創(chuàng)新:為增加鏵式犁的翻土性能,將鏵體延拓;在犁體前加小前犁或前犁刀,減少整機作業(yè)阻力;用液壓油缸調(diào)節(jié)耕幅
28、及懸掛架橫向位置, 以增加其適應(yīng)性;后一犁體可向上折疊以減少耕幅,翻轉(zhuǎn)機構(gòu)加銷定裝置;鏵式犁和深松機上裝有各種形式的安全裝置;圓盤耙偏角的調(diào)節(jié) 和兩翼機架的折疊用液壓油缸控制,一些圓盤耙產(chǎn)品設(shè)有側(cè)向運輸裝置;將深松技術(shù)和耕翻技術(shù)有機結(jié)合, 使上層20cm內(nèi)的土壤上下翻轉(zhuǎn),下層20-35cm進行間隔深松;為了提高松土性能,在深松柄上增加一層或兩層翼鏟,使土壤形成了上層細碎,下層虛實相間,為作物的生長提供了良好的土壤條件,有利于作物生長。&
29、lt;/p><p> 世界各國大中型拖拉機的功能日趨完善,保有量逐年增加。鏵式犁、圓盤耙和深松機等傳統(tǒng)農(nóng)具產(chǎn)品朝著與147kW以上的大中型拖拉機配套、結(jié)構(gòu)完善和功能 增加方向發(fā)展。</p><p> 耕整機械既要適應(yīng)各種土壤條件,又要滿足不同耕作制度發(fā)展的需求,因此必需不斷地開發(fā)新的工作部件。大公司十分重視工作部件的研究: 在鏵式犁上采用各種類型曲面的犁體及小前犁;圓盤耙上采用各種曲率半徑
30、、不同直徑和刃口形狀的圓盤耙片;驅(qū)動型耕和整地機具的工作部件更是種類繁多。在同一機具上,通過更換部件來適應(yīng)變化的工作條件,既擴大了產(chǎn)品的功能,增強了整機的地區(qū)適應(yīng)性,又減少了使用者的購機投入。其工作部件已經(jīng)標準化、系列化和批量化生產(chǎn)。</p><p> 隨著耕作機械的研究和生產(chǎn),特別是大功率拖拉機的廣泛應(yīng)用,帶動了耕作機械向多品種和系列化方向發(fā)展,向?qū)挿?、高速和高效低耗方向發(fā)展,向電子監(jiān)控、液壓及模塊化設(shè)計等高
31、新技術(shù)方向發(fā)展。因此,與其配套的耕整地機械產(chǎn)品也在不斷拓寬與拖拉機的配套范圍,盡可能減少部件種類和結(jié)構(gòu)型式,通過提高標準化、系列化和通用化的程度來滿足市場需求。</p><p> 由于驅(qū)動型機具充分利用拖拉機功率,能控制對土壤的作用強度,可滿足多種耕作要求,公司都十分重視驅(qū)動型整地機具產(chǎn)品的開發(fā)與生產(chǎn)。目前,已有旋轉(zhuǎn)犁、動力鍬、旋耕機和動力耙等多種耕整地機具利用拖拉機的動力輸出軸,通過機械傳 動驅(qū)動工作部件。同
32、時,還研究生產(chǎn)了由拖拉機動力輸出帶動液壓系統(tǒng),再由液壓馬達來驅(qū)動工作部件的新型耕整地機具?,F(xiàn)有的驅(qū)動型耕整地機具主要有旋耕機和滅茬機等產(chǎn)品, 均由拖拉機動力輸出軸提供動力,帶動回轉(zhuǎn)工作部件完成機具作業(yè)。</p><p> 少耕深松技術(shù)具有減少機具的工作阻力、提高拖拉機作業(yè)效率和減輕對土壤的工作強度等特點,形成虛實相間、用養(yǎng)相結(jié)合的土壤耕層構(gòu)造。虛的部分有利于好氣性細菌繁殖,為作物提供充足的養(yǎng)分,有利于作物生長,
33、地上水較多時通過虛的部分將地表的水分滲入地下, 實的部分有利于閑氣性細菌生長,保持土壤中的養(yǎng)分。干旱時,通 過實部分土壤毛細血管的作用,將地下水吸上地表,供給作物水分 實現(xiàn)了用地與養(yǎng)地相結(jié)合。因此,以少耕、深松代替犁耕的保護性耕作技術(shù)在許多國家得到了大面積推廣應(yīng)用,為保護性耕作的關(guān)鍵技術(shù)一。為適應(yīng)農(nóng)業(yè)生產(chǎn)的需求,公司十分注重對深松工作部件和機具的研制。為改善作業(yè)質(zhì)量和降低阻力,研制出了多種形式的桿尺式深松鏟。在深松機具總體結(jié)構(gòu)上也不斷創(chuàng)
34、新,同時大力發(fā)展深松聯(lián)合作業(yè)機具。</p><p> 目前,國內(nèi)外研究和生產(chǎn)的聯(lián)合作業(yè)機,從結(jié)構(gòu)上可分為緊密型聯(lián)合作業(yè)機和組合型聯(lián)合作業(yè)機:緊密型聯(lián)合作業(yè)機是將其作業(yè)功能進行有機結(jié)合,按整機一體的形式進行合理配置,形成一個獨立完整的機型,其機組設(shè)計合理、結(jié)構(gòu)緊湊、與拖拉機配套合理,有利于拖拉機懸掛作業(yè);將各自獨立的機具構(gòu)成聯(lián)合作業(yè)機具。作 業(yè)時, 根據(jù)不同的耕作制度、不同的土壤條件和農(nóng)藝要求,合理組配,形成不同
35、形式的作業(yè)功能,可提高機具利用率50%以上。因此,組合型聯(lián)合作業(yè)機是近年來國外聯(lián)合作業(yè)機具發(fā)展的方向,主要作業(yè)機具有:耕整地聯(lián)合作業(yè)機具、深松整地聯(lián)合作業(yè)機具、深松耙茬聯(lián)合作業(yè)機和耕整施肥播種聯(lián)合作業(yè)機具等。隨著我國大功率拖拉機保有量逐年增加,對聯(lián)合作業(yè)機具的需求也將加大。因此,既要研制多種工作部件 組合的聯(lián)合作業(yè)機具, 也要研制可分可合的組配式聯(lián)合作業(yè)機具。</p><p> 機電液一體化技術(shù)將在各種耕種機具
